Abstract
The EM-X, a new generation of EM-4, is a distributed memory multiprocessor which has a dataflow mechanism. The dataflow mechanism enables a fine-grain communication packet through the network to invoke and synchronize the thread of control dynamically with very small overhead. In this paper, we present programming with a distributed data structure shared by threads, and its implementation for the EM-X multiprocessor. Threads may communicate and coordinate by leaving data in a global address space. A new distributed data structure, called the Q-structure, is introduced. This can be used as a shared queue in the context of thread-based programming in the parallel programming language EM-C. We also discuss related distributed data structures including Liuda'a tuple space, synchronizing data structure in the dataflow computation model.KeywordsStructure MemoryRemote MemoryTuple SpaceGlobal PointerRemote Procedure CallThese keywords were added by machine and not by the authors.
